Ultrafast charge-transfer-induced spin transition in cobalt-tungstate molecular photomagnets

Photoinduced phase transitions in cyanido-bridged Co-W photomagnets change the spin and charge state of both metal centers. Here the authors show that this process is driven by charge-transfer dynamics followed by spin transition within 130 fs.

Multicore fiber optic imaging reveals that astrocyte calcium activity in the mouse cerebral cortex is modulated by internal motivational state

Astrocyte calcium increases can alter brain state, but their dynamics during different behaviors have not been fully described. Here, the authors use multicore fiber optic imaging in freely moving mice to show that astrocyte engagement in behavior is influenced by the motivational state.

Ultrafast and persistent photoinduced phase transition at room temperature monitored by streaming powder diffraction

Photoinduced phase transitions occur in a variety of materials and allow for the optical control of the materials properties. Here, Herve et al present a streaming powder X-ray diffraction method allowing them to study the ultrafast photoinduced phase transition of Rb_0.94Mn_0.94Co_0.06[Fe(CN)₆]_0.9 within thermal hysteresis.

Ultrafast control of anisotropy

Single-molecule magnets are able to store information through their magnetic anisotropy, making them very promising systems for memory applications. Now, femtosecond-laser-initiated molecular dynamics that modulate magnetic anisotropy have been observed, paving the way for operation on ultrafast timescales.

Molecular motion watched

A laser pulse can switch certain crystals from an insulating phase to a highly conducting phase. The ultrafast molecular motions that drive the transition have been directly observed using electron diffraction. See Letter p.343

Charge transfer driven by ultrafast spin transition in a CoFe Prussian blue analogue

Cyanide-bridged CoFe coordination networks exhibit photomagnetism because of coupled charge-transfer and spin transition. Now, femtosecond X-ray and optical absorption spectroscopies have enabled the electronic and structural dynamics of this light-induced process to be disentangled and show that it is the spin transition on the cobalt atom, occurring within ~50 fs, that induces the Fe-to-Co charge-transfer within ~200 fs.

Thioredoxin 1 moonlights as a chaperone for an interbacterial ADP-ribosyltransferase toxin

Thioredoxin 1 (TrxA) is an enzyme that reduces disulfide bonds in the bacterial cytosol. Here, the AUs show that TrxA can function as a chaperone of the secreted bacterial ADP-ribosyltransferase toxin TreX independent of redox catalysis.

Coherent structural trapping through wave packet dispersion during photoinduced spin state switching

Ultrafast nonadiabatic chemical dynamics during molecular photo-transformations remain challenging to describe since electronic/nuclear configurations are coupled. Here the authors use time-resolved X-ray absorption spectroscopy to probe the light-induced spin-state trapping dynamics of [Fe(bpy)₃]²⁺beyond the Born-Oppenheimer approximation.

Lactate racemase is a nickel-dependent enzyme activated by a widespread maturation system

Lactate racemase is an enzyme that interconverts the L and D isomers of the common metabolite lactate. Here, the authors show that lactate racemase represents a new type of nickel-dependent enzyme, which is activated by accessory proteins that are widespread among prokaryotic microbes.

Evidence of a causal and modifiable relationship between kidney function and circulating trimethylamine N-oxide

TMAO is known to be atherothrombotic. Here the authors show that i) kidney function is the main determinant of serum TMAO, ii) TMAO increases kidney scarring with TGF-β1 signalling and iii) anti-diabetic drugs with reno-protective properties such as GLP1R agonists reduce plasma TMAO.
